Updating Flex SDK version from 4.0 to 4.5.1 using Flash Builder 4

shaydu — Mon, 08 Aug 2011 19:35:50 +0000

first download the latest SDK from this link.

http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.5

then copy the contents into the sdk folder under 4.5.1. I found this folder here:
C:\Program Files (x86)\Adobe\Adobe Flash Builder 4\sdks

open flash builder 4

go to window > preferences > Flash Builder > Installed Flex SDKs > add

then select your new download folder.

I had to uninstall Flash Player and download a new one due to this error:
This project requires a more recent version of the Adobe Flash Player. You might need to install the Flash Player or reinstall Flash Builder.

This seems to have fixed the problems.

I’m not sure if the updaters do all of this automatically or not:

That will be worth researching first before i do this again.

If IP incorrectly banned, run: service iptables restart

see who was banned:
iptables -nL

/etc/fail2ban/jail.conf contains parameters for each service

after config changes, run service fail2ban restart

Disable Cron Email Notifications in Plesk

shaydu — Mon, 02 May 2011 17:22:55 +0000

In Plesk, under the cron administration page, add a ‘ &> /dev/null’ at the end of any cron jobs to eliminate email output for that command. This should be appended to the linux command itself.
